Rac Rent A Center Rip Off, Scam, Stealing, continuous phone calls, rude employees Kansas City, Missouri

I have had some horrible incidents happen to me in the last 4 years with Rent a Center. In July of 2006 I decided that I needed a computer so without having any credit, I went here.
I bought me a Compaq and I didn't even think about it, just went in faithfully every week and made my payment, at the time the store had good employees, very nice and friendly even if a bit pushy. I completely paid it off without even thinking what exactly did I pay for this computer anyway.
I continued to ignore that thought and went back in to check out what inventory they had in stock, I wanted a laptop.
I believe in 2008 I went in for a laptop and went home with an HP, it was ok but not what I was looking for so I took it back, they sent me home with a very nice looking Toshiba laptop with a very corrupted disk drive, so bad that it couldn't be fixed.
They then sent me home with a white one that I was not happy with at all, but by this time I had already made probably 8 months of payments (every week)!!!
When I took it back, they gave me a good one, a Sony Vaio.
They also restarted all of my payments!!! Not a penny did I get back from the year that I had already paid for because they could not get the laptop that I wanted to begin with.
I found out later that I had already paid $850 dollars on it and still had to pay $43 every week for 52 weeks, 52 WEEKS!!! Add that one up. They took the laptop back, were very rude to me throughout the whole ordeal, called sometimes 5 times a day, banging on the door, leaving voicemails, hateful messages, continually harassing you is pretty much the bottom line.
I am not sure how this company is getting away with all of this bad behavior but I think something needs to be done
